  • the head mounting table 22 is slidably and detachably mounted on the upper surface 10a of the printed circuit board 10, such that a T-shaped guide member 38 and a pair of engagement pins or spring clips 39 ( Figure 5) integrally formed with the lower side of the head mounting table 22 engage guide openings 40 and 41, respectively, formed through the printed circuit board 10 and the guide base 29.
  • the push button lock plate 26 is slidably screwed to the lower side of the guide base 29 by a pair of screws 43 which are inserted through a pair of elongated openings 42 formed through both ends thereof in its longitudinal direction.
  • the push buttons such as the fast forward button 24, the stop button 25 and so on, are located between the guide base 29 and the push button lock plate 26.
  • the push buttons are slidably attached to the printed circuit board 10, such that T-shaped guide members 44 and 45 integrally formed on the upper side of each of these push buttons respectively engage guide openings 46 and 47 formed through the printed circuit board 10 and the guide base 29.
  • the playback button 23 is moulded integrally on the head mounting table 22.
  • the slide members such as the head mounting table 22, the fast forward button 24, the stop button 25, the push button lock plate 26 and the like are biased in the return direction by return springs 48.
  • the motor 18, the reel table 13b and the capstan 17 are coupled or connected by a belt 49 ( Figure 4).
  • the tape cassette 1 is horizontally loaded onto the upper surface 10a of the printed circuit board 10, the reel hubs 2a and 2b are respectively engaged with the reel tables 13a and 13b, and the cassette tape 3 is extended to the capstan 17.
  • the tape cassette 1 engages the cassette positioning pins 16a and 16b, is carried on the cassette mounting guide 14, and is held thereon by the cassette holding spring 15 so that the tape cassette 1 is horizontally placed at a predetermined position at a predetermined height from the guide base 29 as a reference.
  • the head mounting table 22 is slid to the solid-line position against the spring force of the return spring 48, whereby a lock pin 51 integrally formed on the lower side of the head mounting table 22 is locked to a lock opening 52 of the push button lock plate 26.
  • the magnetic head 19, the pinch roller 20 and the tape guide 21 are inserted into the tape cassette 1, whereby the magnetic head 19 and the tape guide 21 come in contact with the cassette tape 3, and the cassette tape 3 is closely engaged with the capstan 17 by the pinch roller 20.
  • a switch (not shown) mounted on the printed circuit board 10 is operated by the head mounting table 22, thereby to drive the motor 18 with the result that the reel table 13b and the capstan 17 are rotated.
  • the cassette tape 3 is transported at a constant speed by the capstan 17 and thereby a predetermined playback is carried out.
  • the switch When the fast forward button 24 is depressed, the switch is operated similarly, and the motor 18 is actuated so that the cassette tape 3 is transported in the fast forward mode by the reel table 13b.
  • the printed circuit board 10 and the guide base 29 are coupled to each other as earlier noted.
  • the printed circuit board 10 and the guide base 29 are vertically coupled with a spacing or clearance 55 therebetween in the vertical direction.
  • the insertion openings 34b is constructed as a reference opening (that is, an opening whose diameter is substantially equal to the diameter of the cassette mount base table 56b).
  • the other insertion opening 34a is constructed as an elongated opening. The pitch displacement of the insertion openings 34a and 34b caused when the printed circuit board 10 is warped can thus be absorbed, so as thereby to protect the cassette positioning pins 16a and 16b from the influence of warping of the printed circuit board 10.
  • the head mounting table 22 is carried on the upper surfaces of the pair of projections 37, which are integrally formed with the guide base 29 on its upper surface, and is slidably mounted on the upper surface 10a of the printed circuit board 10 as earlier described.
  • the head mounting table 22 can slide on the guide base 29 so that it is floated from the upper surface 10a, which is the wiring pattern surface of the printed circuit board 10, by a predetermined height H (see Figure 5).
  • the head mount base table 22 can slide very smoothly.
  • the cassette positioning pins 16a and 16b for restricting the height of the tape cassette 1 are provided on the guide base 29 which supports the head mount base table 22 above it by the protrusions 37, the heights of the tape cassette 1 and the magnetic head 19 can be accurately maintained on the basis of the guide base 29. As a result, independent of influences such as warp of the printed circuit board 10 and so on, the height of the magnetic head 19 relative to the cassette tape 3 can be accurately maintained.
  • the printed circuit board 10 and the guide base 29 are coupled with each other by using the pair of screws 43, if the engaging method using the engagement pin or spring clip 32 and the opening 33 is adopted as shown in the embodiment of the invention, the printed circuit board 10 and the guide base 29 can easily be coupled and/or detached with a one-touch action.
  • the protrusion 54 shown in this embodiment is made of an elastic material, such as rubber, it is possible to provide a buffer property between the printed circuit board 10 and the guide base 29.
  • the present invention is not limited to a cassette tape recorder which uses a compact tape cassette, but can be applied to various kinds of cassette tape recorders using a micro-tape cassette and various other kinds of tape cassettes.
  • the embodiment described utilizes as a chassis the printed circuit board which may become warped due to temperature or dimensional variations, the perpendicularity of the capstan relative to the cassette tape can be prevented from being changed by such warping. Accordingly, it is possible to prevent the running of the cassette tape from becoming unstable, so good recording and reproducing characteristics and high reliability can be achieved.
